Package



Package include: micro USB cable, bag - cover, manual, headlamp itself

Appearance



The luminous part of the lamp is a flexible board with 14 SMD diodes, in the front part ten diodes are located under domes of lenses of a cunning form, all of this is wrapped by a transparent plastic tube and glued to a plastic base (the purpose of which is eyes protection from glare), and then on the strap. How do diodes live with such a heat sink? I think not very good.



On the sides are connectors.

The connector is made without any protection against water. The connection between battery block and cable is not stable, this with the PWM gives a very nasty squeak under the ear.

Control wheel

The head strap has acceptable quality.
The strap can be disconnected from the battery pack.

There is also a latch that allows you to open the head strap. On sale there is an extension cord with the help of which the lantern can be mounted on the belt.


The charge indicator has 5 leds.

Weight and dimensions

The weight of the headlamp is 155g. not 130g!
The size of the battery block is 77 * 53 * 34 for 1X18650 it is a lot.

Modes and UI

All control is carried out by a wheel on the battery pack. A long press turns on / off the flashlight.
Rotation changes the brightness.There are 28 modes. To go from the first to the last wheel you need to turn 1 1/8 turn.
The current in the minimum mode is 40mA at a maximum is 1.45A step is about 50mA.

Maximum mode stabilization.

So there is no stabilization at all . Runtime is less than declared 2.30 vs 3h. The first section of graph with a rapid decrease in brightness is likely due to overheating of the leds.
In maximum mode, strap heats up to ~ 50C.

It will warm up your head well)

Charging and battery

Maximum charging current is 0.9A. Measured(lii500) capacity is 2900mAh. Charging time is 5 hours. During the charge the indicator flashes .The number of LEDs corresponding to the current charge. After the termination all 5 diodes burn constantly.
In the process of charging, the functionality of the flashlight does not change.

Light

The distribution of light is quite interesting.
lantern pointing at the wall:


Directed along the wall:

The side illumination is not visible against the background of the central spot, but it is, due to 4 diodes without optics.
The main light spot consists of two parts. One is under the feet, the second is directed forward, between them there is a failure in illumination.

Due to the very wide light in the forest, the minimum comfortable illumination starts from the middle of the adjustment range.

  • Spectrum:* At different points in the beam, the spectrum changes from

    CCT = 9281K (Duv –0.0078)
    Color Rendering Index (Ra) = 88.1
    R1 = 89.8 R2 = 91.6 R3 = 88.9 R4 = 90.7 R5 = 88.1 R6 = 81.9 R7 = 90.7
    R8 = 83.1 R9 = 46.0 R10 = 77.7 R11 = 89.9 R12 = 58.9 R13 = 90.7 R14 = 95.5

    to

    CCT = 4701K (Duv 0.0131)
    Color Rendering Index (Ra) = 78.9
    R1 = 73.9 R2 = 84.4 R3 = 95.6 R4 = 76.0 R5 = 75.0 R6 = 80.0 R7 =

    in the yellow area.

PWM : is present in all modes. Frequency 1kHz. At maximum, the fill factor is 1/2.
at the maximum:

at the minimum:

Exposure the same 1 / 100s

Maximum output

The average current on each diode is ~ 100mA. Efficiency will be the same as at current 200mA
For the stated LEDs at this current flow is ~ 53 lm.
So it gives us about 750 lm without taking into account losses (and with such a system they can easily be 20%) and the fact that such current take place only with a fully charged battery.

Light meter shows 250kd at full charge,it is about 32m ANSI. Here everything is true.

Disassembly
One of 3 screws. It does not look reliable.

Two others are under the wheel:

Inside:


Pay attention to the charge indicator, from the outside this big display can be seen only through tiny holes.


Conclusion.

Headlamp is very specific , with many issue

- Low-frequency PWM on all modes.

- Scary color artifacts.

- disgusting squeak

- Lack of waterresistance.

- Official spec is not true

- Lack of heat dissipation from the LED.

  • Price.

I see only pluses

- Comfortable headband

  • Light distribution is convenient. (Although very uneconomical)

In fact, only the latest feature distinguishes it from of Chinese lanterns for <10 $.
It feels like a kickstarter project: a beautiful presentation, good idea, but devil in the detail

Thanks for the very interesting review! Pity that it turned out like this. Might have been an alternative to other “sporting goods store” headlamps.

Ya man, Thanks for the review, I was really considering getting it. Might be a decent headlight one day. But it seems to earlly in its devolpment.

Thanks for the clear review, that is not a very good headlamp!

I read in someone else’s review that the height of the beam when the headlamp sits comfortable on your head was on a different height than the ideal view direction of the eye. Could be that the reviewer had an odd-shaped head :party: but it seems that the beam height can not easily be adapted.

:confounded:

6

My thoughts exactly…
What a POS…

7

Yes it is not possible to change direction of beam but it is very wide. So shape of beam is convenient in my opinion, but pwm and color make it awful.

8

Hey! That was my head in question…

The angle of the beam seemed to be pointed straight out from the band, and unless you have a Frankenstein head with a cliff-like forehead, that means it’s pointed slightly upward. So you either angle your head slightly down and eyes slightly up, or just lower the band to your eyebrows to “straighten” the beam.

I was wondering about the yellow-light band at the bottom, though. No idea if that was mainly due to the LEDs or the optix or just both.

And honest to B’harni (pbuh!), I don’t hear even the 1kHz pwm hum. Just turned it on, held it right to my ear, and… nothing.

Then again, I still hear “Yanni”…

I was mainly testing this critter indoors, and its use as a mule (or close to it) was what really impressed me. If I were outdoors and needed more throw, I’d probably stick with my trusty ol’ Boruit. Easy to swap TIRs, and got a nice 60° one in mine now.

Being that I was only using it indoors, I didn’t even think about its waterproofness, or lack thereof. Outside, in the rain, or in a cave(!), sure, that’d be pretty horrible.

I had mine cranked up to full for at least 5min or so, and didn’t feel the band warm up that much. 50°C I think I would’ve felt for sure, though! Most times I used it (as I use most of my other lights, handheld and headlights), I only had it about half-power.

Still gotta say, despite the yellow band of light at the bottom, I really liked the spread. It was like having the overhead room-lights on with the nice even spread of light.

Nice really thorough test, though. I didn’t take apart mine, as I wanted it to keep working. :laughing:
